Question 8 should be y=-5/2x-1. And question 9 should be y=1/2x-7.
Answer:
R=22
Step-by-step explanation:
180-44= 136
136÷2= 68
90-68= 22
180 is angle of the straight line. 44 is subtracted to get angle of only the triangle on the left which is 136. 136 is then divided by 2 since the remaining two angles are equal and you'll get 68. R is part of a right-angled triangle (90°) subtract 68 from that and you will get 22
The answer to the radius is 3 hope it I helped
